With the magnification of the belt conveyor, dynamic analysis and dynamic design have become indispensability means in the design of belt conveyor. In this article, we build the finite-element model of the starting and stopping process, which bases on the multi-driving belt conveyor system, and the dynamic calculation method of multi-driving system basing on power tracing. According to the reasonable starting curve, we start the first driving/drive, and then the rest drives trace the first driving in order. We bring forward the starting curve of trapezium acceleration from the existing S-curve. We develop the dynamic analysis software of belt conveyor and test the correctness of its calculation and software by the computer simulation of the actual system. The method had been applied in the system design of 7.6 km belt conveyor in Jincheng city, Shanxi province.
